Results
We found 55 patients with all 16 segmental T2* values normal (>20 ms).
Of the 4 patients with abnormal segmental T2* values,
all showed an heterogeneous MIO (some segments with T2*>20 ms and other segments with T2*<20 ms) and none showed an homogeneous MIO (all segment with T2*<20 ms).
Out of the 4 patients with heterogeneous MIO,
only one had a global T2* <20 ms (Figure 2).
The mean global heart T2* value was 34.4 ± 6.2 ms.
The mean mid-septum T2* value was 37.1 ± 8.7 ms.
Global heart and mid-septum T2* values were significantly correlated (R=0.798; P<0.0001).
We did not find significant differences among sickle-thalassemia regularly (N=20),
sporadically (N=32) and no transfused (N=7) in the T2* global value (33.4 ± 7.3 ms versus 35.5 ± 5.4 ms versus 32.4 ± 6.3 ms; P=0.425).
There was a statistically significant positive correlation between global T2* and age but with poor linearity (R=0.368; P=0.004) (Figure 3).
The global T2* value was not significant different between males and females (35.6 ± 4.9 ms versus 35.2 ± 7.2 ms; P=0.118).
